Abstract Microplastics (MPs) as emerging contaminants have a global occurrence, including both terrestrial and marine ecosystems. Soil enzymes contribute to maintaining ecosystem multifunctionality, for example, nutrient cycling, organic material decomposition, carbon climate regulation. Our present review highlights the impacts of MPs on soil enzyme activities, influencing factors, underlying mechanisms. Increasing findings confirm that can change activities range involved in biogeochemical cycling C N. However, current results are highly controversial. The effects vary from significant nonsignificant dependent polymer type, biodegradability, dosage, size, shape, aging degree MPs, exposure conditions. Compared traditional biodegradable generally show more pronounced effects. via different pathways. On one hand, directly structure, leading alterations activity. other create unique habitats, provide sources specific functional microbes producing enzymes, release plastic additives pollutants disturbing production these enzymes. Furthermore, alter physicochemical biological properties, availability substrates, plants fauna, regulating their functions. In conclusion, regulate pose profound impact multifunctionality.

Microplastics pose a serious ecological threat to agricultural soils, as they are very persistent in nature. can enter the soil system different ways and present shapes concentrations. However, little is known about how plants react microplastics with concentrations shapes. To this end, we conducted factorial pot experiment wheat (Triticum aestivum L.) which mixed polystyrene (PS) (bead, fiber powder) at of 0, 1, 3 5%. Although all PS significantly reduced morphological growth traits, powder shape was microplastic that plant height (by 58–60%), fresh biomass 54–55%) dry 61–62%) most, especially 3% 5% compared 0% PS. Similar negative effects were also observed for root length weight concentrations, regardless shape. A concentration-dependent reduction leaf area index (LAI) observed. Interestingly, increasing concentration tended up-regulate activity antioxidant enzymes shapes, indicating potential complexity highly time-dependent response related various reactive oxygen species (ROS). Importantly, caused significant chlorophyll pigmentation photosynthetic rate. For transpiration rate, stomatal conductance intercellular CO2 concentration, on increased increase Overall, concluded higher potentially more devastating physiological biochemical attributes wheat, evidenced by pigments gas exchange parameters We recommend further research experiments not only translocation but tissue-specific retention sizes crops fully understand their impact food safety.

The presence of microplastics (MPs) in agricultural soils substantially affects the growth, reproduction, feeding, survival, and immunity levels soil biota. Therefore, it is crucial to investigate fast, effective, accurate techniques for detection MPs. This work explores integration terahertz time-domain spectroscopy (THz-TDS) with machine learning algorithms develop a method classification First, THz spectral image data were preprocessed using moving average (MA). Subsequently, three models developed, including random forest (RF), linear discriminant analysis, support vector (SVM). Notably, SVM model had an F1 score 0.9817, demonstrating its ability rapidly classify MPs samples. Three regression models, namely, principal component (PCR), RF, least squares (LSSVM), developed polymers soils. Six feature extraction methods used extract relevant parts containing key information. results study showed that accuracies PCR, LSSVM greater than 83%. Among them, RF highest overall accuracy. PE-UVE-RF best performance Rc2, Rp2, root mean square error calibration, prediction values 0.9974, 0.9916, 0.1595, 0.2680, respectively.

Microplastic (MP) pollution has garnered widespread attention because of its negative effects, even in the most remote areas Earth. However, research on MP deposition deserts, which account for 45% Earth’s total land area, remains limited. Desert environments, characterized by large temperature fluctuations, high ultraviolet radiation, and strong winds, accelerate degradation, aging, wind erosion, deposition, migration microplastics (MPs). In desert regions, MPs originate primarily from human activities, such as tourism waste, agricultural mulch residues, artificial water storage systems. Additionally, transport, entrainment, atmospheric wildlife further influence abundance these areas. As soils intensifies, it negatively affects local microbial activity, crop yields, reproduction rare wildlife, climate. response, mitigation strategies, biodegradation, organic alternatives, wasteland transformation, have been proposed. challenges remain, including a lack specific data limited economic incentives environmental protection measures. Drawing existing research, this paper provides comprehensive summary main sources areas; factors their fate; detrimental effects ecosystems (including microorganisms, animals, plants, climate); current response Valuable insights are extracted available data, highlighting status offering useful reference future area.

The widespread presence of microplastics (MPs) is growing concern for both the scientific community and public. Contemporary research increasingly focuses on ecosystem transformation global climate change. We conducted a literature review, consisting 46 studies, to investigate consequences MPs’ influence carbon cycle in different soil types across various ecosystems. MPs can affect cycling compounds other biogenic elements by impacting microbiome, enzyme activity, plant growth, litter decomposition, more. majority authors report increased CO2 and/or CH4 emissions soils containing MPs. However, some studies demonstrate opposite or neutral result, outcomes differ even within single study depending type type, form, size used. Further clarification development our understanding regarding impact ecosystems remain crucial, taking into account inclusion as wide variety possible future research.
